Disease Profile


Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Age of onset






Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.


Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.


dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.


recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.


Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.


Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Scleredema adultorum; Scleredema adultorum of Buschke; Scleredema diabeticorum;


Scleredema is a form of cutaneous mucinosis, a diverse group of rare skin conditions that are characterized by an accumulation of mucin (a jelly-like complex carbohydrate substance) in the skin. Signs and symptoms of this condition include hardening and thickening of the skin which may restrict movement. Skin in affected areas may be red or brown and often has an 'orange-skin' appearance. There are three forms of the condition which vary by disease course and long term outlook (prognosis). Although the underlying cause is currently unknown, each form is associated with a different condition: infection (type 1), blood abnormalities (type 2), and diabetes (type 3). In some cases, scleredema resolves spontaneously on its own, while in other affected people, the condition persists for long periods of time. Due to the rarity of the condition, there is no standard treatment.[1][2]
